While there is no native YouTube app (yet) for PS4, there's a way to get back an almost exact replica. Almost.

It's not as easy as a native app. It's not as direct, but it's at least acceptable.

1) Open the Internet browser
2) Go to "http://www.youtube.com/tv"
3) You'll now see the 'native YouTube app' that we had before

Additional steps for 'optimal' experience:

- Use the square button to go full screen
- If used frequently, the "YouTube TV" page will show up on your "Frequently Used Pages" list, for even quicker access

Bookmark
You can also create a bookmark for quick access. When you are on the webpage "http://www.youtube.com/tv", press the "Options" button and select "Add boodmark".

Once it is in your "Frequently Used Pages" or "Bookmarks" list, it's not that bothersome. Sure, it is still one or two steps more than before - but at least we can use YouTube.

Extra Hint for an even better YouTube experience on your TV
In the YouTube app go to "Settings" and than "Pair Device". It allows you to pair the YouTube page with your smartphone, tablet or PC. This way, you can select a video on your smartphone or tablet, while you watch it on your TV. :)

I was wondering why the Xbox One YouTube app had such a terrible UI that didn't match anything else on the system and noticeably worse performance than other apps. Now I see that it was basically just a bookmark/webview for this page.

Wish they would design native apps for these consoles, they certainly have the resources.

Didn't even realize youtube worked at all. I was just fooling around with the web browser, went to youtube, it said that I need Flash to play videos and that it was incompatible with my device, clicked on a video anyway and boomla, it works.

And the method in the OP makes it even better. Navigates faster than the PS3 app and hopefully it's reliable. Sucked all kinds of balls for longer videos.

Yikes, it looks the same as the xbox one app, which is not that great in terms of UI.

No it doesn't? I don't have one so that picture may not be accurate.

If Netflix worked together with MS to make an interface fitting of the Xbox, I always assumed they did the same with the Playstation 3. Since the rail has the same design philosophy as the new PS Store.

I think it may be the case that youtube.com/tv is the same thing as the app on any TV platform. The app is more than likely made in HTML5 with CSS/JavaScript and the website is no exception to this. The website looks, works, and feels exactly the same as the YouTube app on any TV platform. So the YouTube app is essentially youtube.com/tv anyways.

The only difference when the "app" (or rather web app) comes to the PS4 is that it'll be treated as an app with it's own icon on the PS4, not something you have to go through the browser for.

How did you trigger that? I've been using the Youtube TV page and it's been pretty damn good. Multiple tabs, perhaps?

Just used the /Tv method in the OP, was browsing through my subscriptions, watched a bit of video, tried to watch another video and crash. Nothing out of the ordinary.
No other tabs. No other games or apps.

This works better than the native app for PS360 for one single reason: It allows you to go to a video at whatever time you want. On PS360 all you can do is fast forward in small increments[with shoulder buttons, somebody correct me if I'm wrong] while this way on PS4 you can just use the cursor to point to a spot on the timeline and you're there.

Very helpful for longer videos. I fell asleep watching the Giantbomb Friday program and now I can go right where I left off. If this was on PS360, I wouldn't have bothered.
